Chapter 5: Plugging into a Target System
Configuring the Emulator for In-Circuit Operation
Step 10. Choose the correct target memory
access size
Whenever the emulator accesses either target memory or an on-chip location, it
uses the monitor program to do so. The monitor program will use either a
"MOVE.B" or "MOVE.W" instruction for this access. You can control this by
answering the configuration question:
Target memory access size?
as either "bytes" or "words". The default value is "bytes", and this should be
acceptable for most cases. There are cases, however, where a target system design
allows only word accesses to a particular area of memory, and you may wish to
answer this question as "words". You may also find that you need the access size
set to "bytes" sometimes and "words" at other times. If you find that this is the
case, you can use the commands:
pod_command "mo -ab" <RETURN>
to set the access size to bytes, or
pod_command "mo -aw" <RETURN>
to set the access size to words. This will allow you to control the access size
without having to modify your configuration.
Note
If you find that you need to change the access size often, you may want to create an
action key for each size in the Graphical User Interface, or create two command
files that contain the appropriate pod_command commands.
